Two Giant Dinosaurs Have Towered Over This California Highway Stop Since the 1970s

Windmills spinning on both sides of a long desert freeway are not usually followed by a Brontosaurus, but that is exactly what happened on a recent drive. A giant T. rex the size of a building appeared next, and I nearly missed my exit.

These roadside dinosaurs have been standing in California for years, and seeing them in person hits differently. They are huge, oddly charming, and painted in colors that change with the seasons, which makes every visit feel slightly new and amazing.

I had heard about them for years, but nothing prepares you for the scale. A stop that was supposed to take ten minutes stretched into over an hour of wandering.

The desert stretches out flat and bright around them, and the freeway hums with traffic that mostly speeds past without a second glance. Take the exit next time.

You will not regret it.Up close, the details are even stranger, especially when you realize these enormous creatures were built as roadside attention-grabbers rather than polished theme park attractions.

Walking beneath them feels wonderfully old-school, a reminder of when highway stops competed for travelers with whatever oversized idea could make drivers hit the brakes.

Dinny the Brontosaurus and His Eleven-Year Build

Eleven years. That is how long sculptor Claude Bell spent building Dinny, the enormous Brontosaurus that greets you first when you pull off the freeway.

Construction started in 1964 and did not wrap up until 1975, which explains why the details feel so hand-worked up close. Dinny stretches roughly 150 feet from nose to tail, and standing beside one of his legs makes you feel comically small.

Bell used a steel framework, an expanded metal grid, and sprayed concrete to shape the body, often salvaging materials left over from the Interstate 10 construction happening nearby. The whole project cost around 300,000 dollars, a staggering figure for a roadside sculpture at the time.

What surprised me most was the texture. The concrete has ridges and seams that catch the desert light, and you can trace the shape of the metal underneath in places.

Walk a slow lap around him before you do anything else. From the back, with the mountains rising behind, Dinny looks less like a novelty and more like a genuine piece of outsider art built by someone who really cared.

Climbing Inside Mr. Rex for the Desert View

Mr. Rex came later, built between 1981 and 1986, and he is the one you can actually climb. Entry is near the tail, then three flights of stairs take you up through the body and into a chamber inside the head.

The staircase is narrow and warm, and there is something genuinely funny about huffing your way up the inside of a dinosaur.

At the top, small openings frame the surrounding landscape: the freeway traffic humming below, the wind turbines turning in the pass, and the brown ridges of the San Gorgonio area beyond. It is a strange, wonderful little viewpoint that no guidebook could really prepare you for.

Claude Bell originally imagined a slide running down the tail, which sadly never happened. He also dreamed of giving Dinny glowing eyes that could spit fire, another idea that stayed on paper.

At about 65 feet tall, Mr. Rex towers over everything on the property. Bring a phone or camera, because the view out of his mouth is easily the most memorable photo you will take here, and the light is best in late afternoon.

The Gift Shop Tucked Inside a Dinosaur’s Belly

Shopping inside an animal is not an everyday experience, but that is exactly what happens at Dinny. His belly holds a gift shop and a small museum space, reached by walking up under his body.

The ceiling curves overhead, and you can see the structure of the sculpture from the inside, which I found weirdly fascinating.

Shelves are packed with dinosaur toys, plush figures, jewelry, magnets, and t-shirts. There are geodes too, the kind you take home and crack open yourself, which feels like a proper souvenir rather than a dusty keychain.

A second gift shop sits within the museum area, so if you miss something in one, check the other. The vibe leans delightfully old-school, a little retro, with merchandise stacked high rather than styled for social media.

Here is the part worth knowing: you do not need a ticket to walk up, look at the two big dinosaurs, and browse the shop. Plenty of travelers stop for twenty minutes, grab a photo and a souvenir, and get back on the road feeling pleased with themselves.

Mr. Rex’s Dinosaur Adventure and the Herd Out Back

Behind the two giants sits a fenced area that most freeway visitors never realize exists. Mr. Rex’s Dinosaur Adventure is an outdoor museum holding more than 70 additional dinosaurs, scattered along paths through the desert grounds.

Some stand perfectly still. Others move in slow, gentle robotic motions that make younger kids stop in their tracks.

I expected maybe a dozen figures and was genuinely surprised by how many there were. The variety helps: long-necked giants, spiky armored types, small raptors hiding near the edges of the path, all painted in bright colors that pop against the pale ground.

Plan on spending an hour or two if you have children with you. Families regularly report letting toddlers burn off energy here after a long stretch of highway, and it works well for that.

Shade is limited, so a hat and water bottle are smart additions, especially in warmer months. Pets are welcome on the property, but they must be leashed and carried while inside the exhibit areas, so keep that in mind if your travel buddy has four legs.

Digging for Treasure in the Sandpit and Sluice

Kids lose their minds over this part, and honestly, I understood why. A large sandpit serves as the dino dig, where children sift through sand hunting for rocks marked with dinosaur names.

Find one, bring it to the counter, and trade it for a prize. Simple idea, endlessly entertaining for anyone under ten.

Nearby, a fossil and gemstone panning sluice lets visitors wash away sand with running water to reveal shiny stones and small fossils underneath. Watching the water carry off the grit while something sparkly appears is oddly satisfying, even for adults pretending they are only supervising.

Bring a small towel or wipes, because hands get sandy and wet fast. Loose clothes and closed shoes make the whole thing easier too.

What I liked is how low-tech it all feels. No screens, no flashing lights, just sand, water, and the thrill of finding something.

If your road trip has been heavy on sitting in a car, this is the release valve. Ten minutes at the sluice tends to reset everyone’s mood before the drive continues.

Seasonal Paint Jobs and Holiday Light Nights

Regulars who drive the 10 often say the fun part is guessing what color the dinosaurs will be this time. The paint changes throughout the year, matching holidays and seasons.

Hearts appear around Valentine’s Day. Spring brings flowers blooming across Dinny’s flanks, while Easter designs show up in pastels.

Come December, Mr. Rex sometimes gets a red suit and beard treatment and becomes Santa Rex, which is exactly as ridiculous and delightful as it sounds.

During the holiday season, the park also runs Dinosaur Nights in Lights, stringing twinkle lights across the grounds so the whole place glows after dark. Seeing a 65-foot dinosaur wrapped in fairy lights in the middle of the desert is not something you forget quickly.

If you pass this way more than once a year, the changing designs give you a reason to stop again. I met the attraction in spring colors and immediately wanted to come back in winter.

Check the hours before an evening visit, since weekends run later than weekdays, with Saturday and Sunday closing at 7 pm rather than 5 pm.

Movie Fame, Road Trip Timing, and Getting There

Film fans arrive with a specific mission. The dinosaurs appeared in the 1985 movie Pee-wee’s Big Adventure, and plenty of visitors come purely to stand where those scenes were shot, especially inside the T-rex head.

They have also turned up in other films, television shows, commercials, and music videos over the decades.

The backstory adds another layer. Claude Bell bought the land in 1946 and built the dinosaurs to draw customers to his Wheel Inn restaurant, which opened in 1958.

He had previously sculpted concrete figures at Knott’s Berry Farm, and his inspiration came from childhood memories of Lucy the Elephant in Atlantic City.

Bell passed away in 1988, but his creations kept going and remain a Southern California landmark.

Practical notes: parking is plentiful, the freeway ramps here can be tight, so take them slowly. Mornings are cooler and quieter, and the site opens at 9 am daily.

Pair it with a trip toward Palm Springs or Joshua Tree and it becomes the perfect leg-stretch stop.
